====== 임시 시스템 제작 ======
젠투로 치면 Stage 1에 해당하는 과정. 꽤 복잡하기 때문에 일일이 문서로 작업 과정을 기록하여, 혹여 작업이 중간에 중단된 후 재개되더라도 손쉽게 재추적할 수 있도록 한다. 또한 이전 과정을 반복해야 할 경우를 대비하여 미리 작업 내용은 쉘 스크립트하여 보관한다.

모든 스크립트의 실행 디렉토리는 $LFS/sources 로 간주한다. 

64비트 설치라면 /tools/lib에 /tools/lib64 symlink를 걸어둔다.
  # mkdir /tools/lib
  # ln -s /tools/lib /tools/lib64

lfs 과정중 $LFS 에 생기는 모든 디렉토리에 대해 사용자 'lfs'가 권한을 가지는지에 대해 확인하라.
